Ocean Rush, where have you been all my life? It's gorgeous! Ocean rush is a medium blue holo. A lot of the blue holos are a pale blue and if I don't have them right next to a silver holo, I almost can't tell it's supposed to be the blue version (I'm looking at you Nfu Oh 65).
Outdoors, full sun
A word of advice, don't even try to put this on without a base coat like Aqua Base or it will be impossible to apply. While you do need a base coat made for holos, top coat isn't necessary. It dries nice and shiny, so there's no need to worry about destroying the holo with a top coat.
I love this polish so much, I think I need to invest in the rest of the collection.
This is 2 coats.
